Oozie cannot find custom action jar

[#1]

I get the error that oozie cant find the custom action class when I run the job. This is how I added my custom action jar to oozie : - stoped oozie - added classname to oozie.service.ActionService.executor.ext.classes in oozie-site.xml - copy cutom.jar to /usr/hdp/current/oozie-server/libext/.

- /usr/hdp/current/oozie-server/bin/oozie-setup.sh prepare-war - started oozie back Error :

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/CustomActionClass

I understand that new actions are to be added as ext.classes and action jars in libext folder. Am I missing something here ? Also how are libext jars different from sharelib jars ?

Oozie didnt have access to hbase jars, added them manually to libext/ folder and created the oozie.war again and it worked.
